AXLE-LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 572,276, dated December1, 1896. Application filed November 1, 1895- Serial No. 567,593. (Nomodel.)

To all whom it may concern.-

Be it known that 1, JOHN REICHENBAOH, a citizen of the United States,residing at Egg Harbor City, in the county of Atlantic and State of NewJersey, have invented certain new and useful Improvements inAxle-Lubricators; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in axle-lubricators of that classin which an oilfeed cup is connected with the axle and the oil is fed bygravity to the part of the axle requiring lubrication.

The object of my improvements is to provide a lubricator which may bereadily attached to vehicles now in use, which will be effective andcertain in its action, which is not likely to get out of order by thejarring of the vehicle, which does not require a special construction ofthe wheel, and which can be furnished at a small cost. The manner inwhich I secure these desirable results is set forth in the followingdescription, and the construction of the device is clearly shown in theaccompanying drawings, in which Figure 1 is a longitudinal sectionalView of one end of a vehicle-axle and my improved lubricator attachedthereto. Fig. 2 is a detail of the construction and arrangement of theclip used with my device.

Like reference-numerals indicate like parts in the views.

The iron or steel axle 1, which is of the ordinary square form,terminates in the spindle 2 and has clipped to its upper side the woodenbolster Between the axle and the spindle and formed therewith is thespindlecollar 4. Along the upper side of the spindle is the oil-groove5, and through the collar 4 is an oil-hole 6, with which the oil-groove5 communicates on the spindle side of said collar. On the opposite sideof said collar and running from said oil-hole along a groove cut in theunder side of the bolster 3 is an oil-tube 7, which is bent at 8 andextends vertically through a suitable hole in the bolster 3, terminatinga short distance above the upper side of said bolster.

Surrounding the axle 1 and bolster a a short distance from the collar 4is the clip 9, of the usual form, except that from the upper portion ofsaid clip is an open extension or boss 10, which is threaded internally,and through i said boss extends the vertical end of the oiltube 7.

Placed above the clip 9 and screwed into the boss 10 is the oil-cup 11,which is provided for this purposewith an externally-threaded pipe 12,the upper end of which is slightly above the bottom of the oil-cup 11.The vertical end of the oil-tube 7 also extends to the pipe 12, as shownin the drawings.

The oil-cup 11 has an opening 13 at the top, through which the oil ispoured into the cup, and said opening is closed with a screwcap 14. Inthe center of the top of the oilcup is an opening 15, which isinternally threaded to receive a valve-rod 16, which extends through thecup to the upper end of the oil-tube 7, and by means of said valverodthe flow of oil into said tube is regulated. In warm weather, when thelubricating-oil flows freely, the valve-rod 16 is screwed down so astoalmost close the tube, but in cold weather the conditions are reversed.

It will be seen that my improved lubricator may be applied to any axleof ordinary form by drilling a hole through the spindle-collar andmaking a horizontal and vertical groove in the bolster to accommodatethe oil-tube. It will also be apparent that no amount of jarring willimpair the efficiency of the lubricator.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In an axle-lubricator, the combination with the axle having a perforatedspindle-collar, of a bolster provided with a longitudinal groove and avertical opening connected therewith, an oil-tube inserted in saidgroove and opening, a clip surrounding said axle and bolster, said cliphaving a vertical internally-threaded extension, an oil-cup having acentral exteriorly-threaded extension to engage the extension on theclip, and a valve-rod centrally located in said cup and adapted to beraised and lowered, in the manner and for the purpose described.

In testimony whereof I have signed this I specification in the presenceof two subscribing witnesses.
